Well, you can't get thousands of bucks of costs in GAE if you don't set limits that high. The way I do it: I've set the daily limit to something really high, but something that won't make me go bankrupt (like $100/$200, while I usually spend $5/day). I don't worry about spikes in payments - as the article says, it's not worth to waste my time analysing all the border cases. If a border case happens, I'll deal with it then. It's much worse with Amazon Web Services which has no such easily set limits. I've heard about a guy getting slapped thousands of bucks bacuse of bandwith usage due to some bug.
